More Power: A 6-stroke engine delivers 4 power strokes in 12 engine strokes, a 33% increase over a 4-stroke’s 3 power strokes. Example: 500 HP in a 4.0L NA H6 could become 600 HP.
Efficiency: Potential for better fuel efficiency due to additional power strokes.
Downsizing: More power per liter allows for smaller, lighter engines.
Lower Revving: Produces more power at lower RPMs, enhancing drivability.
Challenges
Complexity/Cost: More moving parts increase manufacturing complexity and cost.
Emissions: Similar to two-stroke engines, managing emissions is a significant hurdle.
Balance: Uneven firing intervals (e.g., not every 180° like a 4-stroke 4-cylinder) create a unique sound but challenge engine balance.
